Here it is: -7/3= -2 1/3 and 9/-4= -2 1/4
Inorder to add these two mixed numbers you would have to find the lowest common denominator (lcd). For this problem the the lcd = 12.
-2 1/3 = -2 4/12 and -2 1/4 = -2 3/12
Therefore, -2 4/12 + -2 3/12 = -4 5/12 ( you are able to add both mixed numbers sinse the lcd are in common)
#2 Any number which can be expressed as a whole number is classified as an integer.
Definition: The set of integers consists of the positive integers, negative integers, and zero.
{...-3,-2,-1,0, 1, 2, 3,.....}
Therefore, -81, 12/3=4, and 18/9 are the only numbers that qualify as an integer
There are two ways you could do it, one involves a calculator and one doesn't.
Calculator:
You would just do 4500 × 1.7 = $7650
Non-calculator:
First you'd divide 4500 by 10 to get 10%, which is 450. Then you'd multiply 450 by 7 to get 3150. Now you just add 4500 and 3150 to get $7650
